Hydrogen Embrittlement Susceptibility of Clad Steel Pipes
View through CrossRef
The objective of the present work has been to evaluate the hydrogen embrittlement susceptibility of 316L - X60/X65 carbon steel hot rolled bonded clad pipes through experimental investigations and cohesive zone numerical simulations. Fracture mechanical testing in air and under in situ electrochemical hydrogen charging revealed little hydrogen influence on the samples with a Ni-interlayer between the clad and the base material, while significant hydrogen influence on the sample without a Ni-interlayer. Cohseive zone simulations were able to predict the detrimental influence of hydrogen on the fracture initiation toughness. The simulations suggest that hydrogen trapped at dislocations are mainly responsible for the embrittlement of the clad pipe base material.
